Thank you, but I cannot take credit for it: this is a standard definition given in any economic text.
But you choose not to continue the discusion with the added restrictions I would impose? That's telling, Quark. Just to satisfy my curiousity, you're a stranger in a strange land here, so to speak, yes? ;)
One can choose not to visit a particular street, and thus reasonably object to paying for lights there.
No, one can choose to say that he would not visit that street. If he reneges on this promise, it is uninforceable.
Still, there are certainly cases where such a claim is most likely true. An honest priest is unlikely to visit the redlight district, for example, and it seems reasonable that we would expect those who run businesses in such a district to foot the bill.

Still, there are certainly cases where such a claim is most likely true. Contracts are not based on likelihood. This is in part because perceptions of likelihood of such events are subjective.
